|
||||
|
||||
Rust has lots of builtin traits that are implemented for its basic types, such as [`Add`],
|
||||
[`Not`] or [`From`].
|
||||
However, when wrapping these types inside your own structs or enums you lose the
|
||||
implementations of these traits and are required to recreate them.
|
||||
This is especially annoying when your own structures are very simple, such as when using the
|
||||
commonly advised newtype pattern (e.g. `MyInt(i32)`).
|
||||
|
||||
This library tries to remove these annoyances and the corresponding boilerplate code.
|
||||
It does this by allowing you to derive lots of commonly used traits for both structs and enums.
|
||||
|
||||
## Example code
|
||||
|
||||
By using this library the following code just works:
|
||||
|
||||
|
||||
```rust
|
||||
#[macro_use]
|
||||
extern crate derive_more;
|
||||
|
||||
#[derive(Debug, Eq, PartialEq, From, Add)]
|
||||
struct MyInt(i32);
|
||||
|
||||
#[derive(Debug, Eq, PartialEq, From, Into, Constructor, Mul)]
|
||||
struct Point2D {
|
||||
x: i32,
|
||||
y: i32,
|
||||
}
|
||||
|
||||
#[derive(Debug, Eq, PartialEq, From, Add)]
|
||||
enum MyEnum {
|
||||
Int(i32),
|
||||
UnsignedInt(u32),
|
||||
Nothing,
|
||||
}
|
||||
|
||||
fn main() {
|
||||
let my_11 = MyInt(5) + 6.into();
|
||||
assert_eq!(MyInt(11), MyInt(5) + 6.into());
|
||||
assert_eq!(Point2D { x: 5, y: 6 } * 10, (50, 60).into());
|
||||
assert_eq!((5, 6), Point2D { x: 5, y: 6 }.into());
|
||||
assert_eq!(Point2D { x: 5, y: 6 }, Point2D::new(5, 6));
|
||||
assert_eq!(MyEnum::Int(15), (MyEnum::Int(8) + 7.into()).unwrap())
|
||||
}
|
||||
```
|
||||
|
||||
## The derivable traits
|
||||
|
||||
Below are all the traits that you can derive using this library.
|
||||
Some trait derivations are so similar that the further documentation will only show a single one
|
||||
of them.
|
||||
You can recognize these by the "-like" suffix in their name.
|
||||
The trait name before that will be the only one that is used throughout the further
|
||||
documentation.
|
||||
|
||||
**NOTE**: You still have to derive each trait separately. So `#[derive(Mul)]` doesn't
|
||||
automatically derive `Div` as well. To derive both you should do `#[derive(Mul, Div)]`
|
||||
|
||||
### Conversion traits
|
||||
These are traits that are used to convert automatically between types.
|
||||
|
||||
1. [`From`]
|
||||
2. [`Into`]
|
||||
3. [`FromStr`]
|
||||
4. [`TryInto`] (nightly-only as of writing)
|
||||
|
||||
### Formatting traits
|
||||
These traits are used for converting a struct to a string in different ways.
|
||||
|
||||
1. `Display`-like, contains [`Display`], [`Binary`], [`Octal`], [`LowerHex`], [`UpperHex`],
|
||||
[`LowerExp`], [`UpperExp`], [`Pointer`]
|
||||
|
||||
### Operators
|
||||
These are traits that can be used for operator overloading.
|
||||
|
||||
1. [`Index`]
|
||||
2. [`Deref`]
|
||||
3. `Not`-like, contains [`Not`] and [`Neg`]
|
||||
4. `Add`-like, contains [`Add`], [`Sub`], [`BitAnd`], [`BitOr`] and [`BitXor`]
|
||||
5. `Mul`-like, contains [`Mul`], [`Div`], [`Rem`], [`Shr`] and [`Shl`]
|
||||
6. [`IndexMut`]
|
||||
7. [`DerefMut`]
|
||||
8. `AddAssign`-like, contains [`AddAssign`], [`SubAssign`], [`BitAndAssign`], [`BitOrAssign`]
|
||||
and [`BitXorAssign`]
|
||||
9. `MulAssign`-like, contains [`MulAssign`], [`DivAssign`], [`RemAssign`], [`ShrAssign`] and
|
||||
[`ShlAssign`]
|
||||
|
||||
### Static methods
|
||||
These don't derive traits, but derive static methods instead.
|
||||
|
||||
1. `Constructor`, this derives a `new` method that can be used as a constructor. This is very
|
||||
basic if you need more customization for your constructor, check out the [`derive-new`] crate.
|
||||
|
||||
|
||||
## Generated code
|
||||
|
||||
It is important to understand what code gets generated when using one of the derives from this
|
||||
crate.
|
||||
That is why the links below explain what code gets generated for a trait for each group from
|
||||
before.
|
||||
|
||||
1. [`#[derive(From)]`](https://jeltef.github.io/derive_more/derive_more/from.html)
|
||||
2. [`#[derive(Into)]`](https://jeltef.github.io/derive_more/derive_more/into.html)
|
||||
3. [`#[derive(FromStr)]`](https://jeltef.github.io/derive_more/derive_more/from_str.html)
|
||||
4. [`#[derive(TryInto)]`](https://jeltef.github.io/derive_more/derive_more/try_into.html)
|
||||
5. [`#[derive(Display)]`](https://jeltef.github.io/derive_more/derive_more/display.html)
|
||||
6. [`#[derive(Index)]`](https://jeltef.github.io/derive_more/derive_more/index_op.html)
|
||||
7. [`#[derive(Deref)]`](https://jeltef.github.io/derive_more/derive_more/deref.html)
|
||||
8. [`#[derive(Not)]`](https://jeltef.github.io/derive_more/derive_more/not.html)
|
||||
9. [`#[derive(Add)]`](https://jeltef.github.io/derive_more/derive_more/add.html)
|
||||
10. [`#[derive(Mul)]`](https://jeltef.github.io/derive_more/derive_more/mul.html)
|
||||
11. [`#[derive(IndexMut)]`](https://jeltef.github.io/derive_more/derive_more/index_mut.html)
|
||||
12. [`#[derive(DerefMut)]`](https://jeltef.github.io/derive_more/derive_more/deref_mut.html)
|
||||
13. [`#[derive(AddAssign)]`](https://jeltef.github.io/derive_more/derive_more/add_assign.html)
|
||||
14. [`#[derive(MulAssign)]`](https://jeltef.github.io/derive_more/derive_more/mul_assign.html)
|
||||
15. [`#[derive(Constructor)]`](https://jeltef.github.io/derive_more/derive_more/constructor.html)
|
||||
|
||||
If you want to be sure what code is generated for your specific type I recommend using the
|
||||
[`cargo-expand`] utility.
|
||||
This will show you your code with all macros and derives expanded.
|
||||
|
||||
## Installation
|
||||
|
||||
This library requires Rust 1.15 or higher, so this needs to be installed.
|
||||
Then add the following to `Cargo.toml`:
|
||||
|
||||
```toml
|
||||
[dependencies]
|
||||
derive_more = "0.13.0"
|
||||
```
|
||||
|
||||
And this to the top of your Rust file:
|
||||
|
||||
```rust
|
||||
#[macro_use]
|
||||
extern crate derive_more;
|
||||

//! # `derive_more`
|
||||
//! Rust has lots of builtin traits that are implemented for its basic types, such as [`Add`],
|
||||
//! [`Not`] or [`From`].
|
||||
//! However, when wrapping these types inside your own structs or enums you lose the
|
||||
//! implementations of these traits and are required to recreate them.
|
||||
//! This is especially annoying when your own structures are very simple, such as when using the
|
||||
//! commonly advised newtype pattern (e.g. `MyInt(i32)`).
|
||||
//!
|
||||
//! This library tries to remove these annoyances and the corresponding boilerplate code.
|
||||
//! It does this by allowing you to derive lots of commonly used traits for both structs and enums.
|
||||
//!
|
||||
//! ## Example code
|
||||
//!
|
||||
//! By using this library the following code just works:
|
||||
//!
|
||||
//!
|
||||
//! ```rust
|
||||
//! #[macro_use]
|
||||
//! extern crate derive_more;
|
||||
//!
|
||||
//! #[derive(Debug, Eq, PartialEq, From, Add)]
|
||||
//! struct MyInt(i32);
|
||||
//!
|
||||
//! #[derive(Debug, Eq, PartialEq, From, Into, Constructor, Mul)]
|
||||
//! struct Point2D {
|
||||
//! x: i32,
|
||||
//! y: i32,
|
||||
//! }
|
||||
//!
|
||||
//! #[derive(Debug, Eq, PartialEq, From, Add)]
|
||||
//! enum MyEnum {
|
||||
//! Int(i32),
|
||||
//! UnsignedInt(u32),
|
||||
//! Nothing,
|
||||
//! }
|
||||
//!
|
||||
//! fn main() {
|
||||
//! let my_11 = MyInt(5) + 6.into();
|
||||
//! assert_eq!(MyInt(11), MyInt(5) + 6.into());
|
||||
//! assert_eq!(Point2D { x: 5, y: 6 } * 10, (50, 60).into());
|
||||
//! assert_eq!((5, 6), Point2D { x: 5, y: 6 }.into());
|
||||
//! assert_eq!(Point2D { x: 5, y: 6 }, Point2D::new(5, 6));
|
||||
//! assert_eq!(MyEnum::Int(15), (MyEnum::Int(8) + 7.into()).unwrap())
|
||||
//! }
|
||||
//! ```
|
||||
//!
|
||||
//! ## The derivable traits
|
||||
//!
|
||||
//! Below are all the traits that you can derive using this library.
|
||||
//! Some trait derivations are so similar that the further documentation will only show a single one
|
||||
//! of them.
|
||||
//! You can recognize these by the "-like" suffix in their name.
|
||||
//! The trait name before that will be the only one that is used throughout the further
|
||||
//! documentation.
|
||||
//!
|
||||
//! **NOTE**: You still have to derive each trait separately. So `#[derive(Mul)]` doesn't
|
||||
//! automatically derive `Div` as well. To derive both you should do `#[derive(Mul, Div)]`
|
||||
//!
|
||||
//! ### Conversion traits
|
||||
//! These are traits that are used to convert automatically between types.
|
||||
//!
|
||||
//! 1. [`From`]
|
||||
//! 2. [`Into`]
|
||||
//! 3. [`FromStr`]
|
||||
//! 4. [`TryInto`] (nightly-only as of writing)
|
||||
//!
|
||||
//! ### Formatting traits
|
||||
//! These traits are used for converting a struct to a string in different ways.
|
||||
//!
|
||||
//! 1. `Display`-like, contains [`Display`], [`Binary`], [`Octal`], [`LowerHex`], [`UpperHex`],
|
||||
//! [`LowerExp`], [`UpperExp`], [`Pointer`]
|
||||
//!
|
||||
//! ### Operators
|
||||
//! These are traits that can be used for operator overloading.
|
||||
//!
|
||||
//! 1. [`Index`]
|
||||
//! 2. [`Deref`]
|
||||
//! 3. `Not`-like, contains [`Not`] and [`Neg`]
|
||||
//! 4. `Add`-like, contains [`Add`], [`Sub`], [`BitAnd`], [`BitOr`] and [`BitXor`]
|
||||
//! 5. `Mul`-like, contains [`Mul`], [`Div`], [`Rem`], [`Shr`] and [`Shl`]
|
||||
//! 6. [`IndexMut`]
|
||||
//! 7. [`DerefMut`]
|
||||
//! 8. `AddAssign`-like, contains [`AddAssign`], [`SubAssign`], [`BitAndAssign`], [`BitOrAssign`]
|
||||
//! and [`BitXorAssign`]
|
||||
//! 9. `MulAssign`-like, contains [`MulAssign`], [`DivAssign`], [`RemAssign`], [`ShrAssign`] and

|

//!
|
||||
//! ### Static methods
|
||||
//! These don't derive traits, but derive static methods instead.
|
||||
//!
|
||||
//! 1. `Constructor`, this derives a `new` method that can be used as a constructor. This is very
|
||||
//! basic if you need more customization for your constructor, check out the [`derive-new`] crate.
|
||||
//!
|
||||
//!
|
||||
//! ## Generated code
|
||||
//!
|
||||
//! It is important to understand what code gets generated when using one of the derives from this
|
||||
//! crate.
|
||||
//! That is why the links below explain what code gets generated for a trait for each group from
|
||||
//! before.
|
||||
//!
|
||||
//! 1. [`#[derive(From)]`](https://jeltef.github.io/derive_more/derive_more/from.html)
|
||||
//! 2. [`#[derive(Into)]`](https://jeltef.github.io/derive_more/derive_more/into.html)
|
||||
//! 3. [`#[derive(FromStr)]`](https://jeltef.github.io/derive_more/derive_more/from_str.html)
|
||||
//! 4. [`#[derive(TryInto)]`](https://jeltef.github.io/derive_more/derive_more/try_into.html)
|
||||
//! 5. [`#[derive(Display)]`](https://jeltef.github.io/derive_more/derive_more/display.html)
|
||||
//! 6. [`#[derive(Index)]`](https://jeltef.github.io/derive_more/derive_more/index_op.html)
|
||||
//! 7. [`#[derive(Deref)]`](https://jeltef.github.io/derive_more/derive_more/deref.html)
|
||||
//! 8. [`#[derive(Not)]`](https://jeltef.github.io/derive_more/derive_more/not.html)
|
||||
//! 9. [`#[derive(Add)]`](https://jeltef.github.io/derive_more/derive_more/add.html)
|
||||
//! 10. [`#[derive(Mul)]`](https://jeltef.github.io/derive_more/derive_more/mul.html)
|
||||
//! 11. [`#[derive(IndexMut)]`](https://jeltef.github.io/derive_more/derive_more/index_mut.html)
|
||||
//! 12. [`#[derive(DerefMut)]`](https://jeltef.github.io/derive_more/derive_more/deref_mut.html)
|
||||
//! 13. [`#[derive(AddAssign)]`](https://jeltef.github.io/derive_more/derive_more/add_assign.html)
|
||||
//! 14. [`#[derive(MulAssign)]`](https://jeltef.github.io/derive_more/derive_more/mul_assign.html)
|
||||
//! 15. [`#[derive(Constructor)]`](https://jeltef.github.io/derive_more/derive_more/constructor.html)
|
||||
//!
|
||||
//! If you want to be sure what code is generated for your specific type I recommend using the
|
||||
//! [`cargo-expand`] utility.
|
||||
//! This will show you your code with all macros and derives expanded.
|
||||
//!
|
||||
//! ## Installation
|
||||
//!
|
||||
//! This library requires Rust 1.15 or higher, so this needs to be installed.
|
||||
//! Then add the following to `Cargo.toml`:
|
||||
//!
|
||||
//! ```toml
|
||||
//! [dependencies]
|
||||
//! derive_more = "0.13.0"
|
||||
//! ```
|
||||
//!
|
||||
//! And this to the top of your Rust file:
|
||||
//!
|
||||
//! ```rust
|
||||
//! #[macro_use]
|
||||
//! extern crate derive_more;
|
||||
//! # fn main () {}
|
||||
//! ```

|
||||
direction or management of such entity, whether by contract or
|
||||
otherwise, or (ii) ownership of fifty percent (50%) or more of the
|
||||
outstanding shares, or (iii) beneficial ownership of such entity.
|
||||
|
||||
"You" (or "Your") shall mean an individual or Legal Entity
|
||||
exercising permissions granted by this License.
|
||||
|
||||
"Source" form shall mean the preferred form for making modifications,

||||
including but not limited to software source code, documentation
|
||||
source, and configuration files.
|
||||
|
||||
"Object" form shall mean any form resulting from mechanical
|
||||
transformation or translation of a Source form, including but
|
||||
not limited to compiled object code, generated documentation,
|
||||
and conversions to other media types.
|
||||
|
||||
"Work" shall mean the work of authorship, whether in Source or
|
||||
Object form, made available under the License, as indicated by a
|
||||
copyright notice that is included in or attached to the work
|
||||
(an example is provided in the Appendix below).
|
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain
|
||||
separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.
|
||||
|
||||
"Contribution" shall mean any work of authorship, including
|
||||
the original version of the Work and any modifications or additions
|
||||
to that Work or Derivative Works thereof, that is intentionally
|
||||
submitted to Licensor for inclusion in the Work by the copyright owner
|
||||
or by an individual or Legal Entity authorized to submit on behalf of
|
||||
the copyright owner. For the purposes of this definition, "submitted"
|
||||
means any form of electronic, verbal, or written communication sent
|
||||
to the Licensor or its representatives, including but not limited to
|
||||
communication on electronic mailing lists, source code control systems,
|
||||
and issue tracking systems that are managed by, or on behalf of, the
|
||||
Licensor for the purpose of discussing and improving the Work, but
|
||||
excluding communication that is conspicuously marked or otherwise
|
||||
designated in writing by the copyright owner as "Not a Contribution."
|
||||
|
||||
"Contributor" shall mean Licensor and any individual or Legal Entity
|
||||
on behalf of whom a Contribution has been received by Licensor and
|
||||
subsequently incorporated within the Work.
|
||||
|
||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the
|
||||
Work and such Derivative Works in Source or Object form.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
(except as stated in this section) patent license to make, have made,
|
||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||
where such license applies only to those patent claims licensable
|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You
|
||||
meet the following conditions:
|
||||
|
||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|
||||
of your accepting any such warranty or additional liability.
|
||||
|
||||
END OF TERMS AND CONDITIONS

|
||||

======
|
||||
|
||||
Semantic version parsing and comparison.
|
||||
|
||||
[](https://travis-ci.org/steveklabnik/semver)
|
||||
|
||||
[Documentation](https://steveklabnik.github.io/semver)
|
||||
|
||||
Semantic versioning (see http://semver.org/) is a set of rules for
|
||||
assigning version numbers.
|
||||
|
||||
## SemVer and the Rust ecosystem
|
||||
|
||||
Rust itself follows the SemVer specification, as does its standard libraries. The two are
|
||||
not tied together.
|
||||
|
||||
[Cargo](https://crates.io), Rust's package manager, uses SemVer to determine which versions of
|
||||
packages you need installed.
|
||||
|
||||
## Installation
|
||||
|
||||
To use `semver`, add this to your `[dependencies]` section:
|
||||
|
||||
```toml
|
||||
semver = "0.6.0"
|
||||
```
|
||||
|
||||
And this to your crate root:
|
||||
|
||||
```rust
|
||||
extern crate semver;
|
||||
```
|
||||
|
||||
## Versions
|
||||
|
||||
At its simplest, the `semver` crate allows you to construct `Version` objects using the `parse`
|
||||
method:
|
||||
|
||||
```rust
|
||||
use semver::Version;
|
||||
|
||||
assert!(Version::parse("1.2.3") == Ok(Version {
|
||||
major: 1,
|
||||
minor: 2,
|
||||
patch: 3,
|
||||
pre: vec!(),
|
||||
build: vec!(),
|
||||
}));
|
||||
```
|
||||
|
||||
If you have multiple `Version`s, you can use the usual comparison operators to compare them:
|
||||
|
||||
```rust
|
||||
use semver::Version;
|
||||

||||
assert!(Version::parse("1.2.3-alpha") != Version::parse("1.2.3-beta"));
|
||||
assert!(Version::parse("1.2.3-alpha2") > Version::parse("1.2.0"));
|
||||
```
|
||||
|
||||
## Requirements
|
||||
|
||||
The `semver` crate also provides the ability to compare requirements, which are more complex
|
||||
comparisons.
|
||||
|
||||
For example, creating a requirement that only matches versions greater than or
|
||||
equal to 1.0.0:
|
||||
|
||||
```rust
|
||||
use semver::Version;
|
||||
use semver::VersionReq;
|
||||
|
||||
let r = VersionReq::parse(">= 1.0.0").unwrap();
|
||||
let v = Version::parse("1.0.0").unwrap();
|
||||
|
||||
assert!(r.to_string() == ">= 1.0.0".to_string());
|
||||
assert!(r.matches(&v))
|
||||
```
|
||||
|
||||
It also allows parsing of `~x.y.z` and `^x.y.z` requirements as defined at
|
||||
https://www.npmjs.org/doc/misc/semver.html
|
||||
|
||||
**Tilde requirements** specify a minimal version with some updates:
|
||||
|
||||
```notrust
|
||||
~1.2.3 := >=1.2.3 <1.3.0
|
||||
~1.2 := >=1.2.0 <1.3.0
|
||||
~1 := >=1.0.0 <2.0.0
|
||||
```
|
||||
|
||||
**Caret requirements** allow SemVer compatible updates to a specified version,
|
||||
`0.x` and `0.x+1` are not considered compatible, but `1.x` and `1.x+1` are.
|
||||
|
||||
`0.0.x` is not considered compatible with any other version.
|
||||
Missing minor and patch versions are desugared to `0` but allow flexibility for that value.
|
||||
|
||||
```notrust
|
||||
^1.2.3 := >=1.2.3 <2.0.0
|
||||
^0.2.3 := >=0.2.3 <0.3.0
|
||||
^0.0.3 := >=0.0.3 <0.0.4
|
||||
^0.0 := >=0.0.0 <0.1.0
|
||||
^0 := >=0.0.0 <1.0.0
|
||||
```

|

|
||||
//! Semantic version parsing and comparison.
|
||||
//!
|
||||
//! Semantic versioning (see http://semver.org/) is a set of rules for
|
||||
//! assigning version numbers.
|
||||
//!
|
||||
//! ## SemVer overview
|
||||
//!
|
||||
//! Given a version number MAJOR.MINOR.PATCH, increment the:
|
||||
//!
|
||||
//! 1. MAJOR version when you make incompatible API changes,
|
||||
//! 2. MINOR version when you add functionality in a backwards-compatible
|
||||
//! manner, and
|
||||
//! 3. PATCH version when you make backwards-compatible bug fixes.
|
||||
//!
|
||||
//! Additional labels for pre-release and build metadata are available as
|
||||
//! extensions to the MAJOR.MINOR.PATCH format.
|
||||
//!
|
||||
//! Any references to 'the spec' in this documentation refer to [version 2.0 of
|
||||
//! the SemVer spec](http://semver.org/spec/v2.0.0.html).
|
||||
//!
|
||||
//! ## SemVer and the Rust ecosystem
|
||||
//!
|
||||
//! Rust itself follows the SemVer specification, as does its standard
|
||||
//! libraries. The two are not tied together.
|
||||
//!
|
||||
//! [Cargo](http://crates.io), Rust's package manager, uses SemVer to determine
|
||||
//! which versions of packages you need installed.
|
||||
//!
|
||||
//! ## Versions
|
||||
//!
|
||||
//! At its simplest, the `semver` crate allows you to construct `Version`
|
||||
//! objects using the `parse` method:
|
||||
//!
|
||||
//! ```{rust}
|
||||
//! use semver::Version;
|
||||
//!
|
||||
//! assert!(Version::parse("1.2.3") == Ok(Version {
|
||||
//! major: 1,
|
||||
//! minor: 2,
|
||||
//! patch: 3,
|
||||
//! pre: vec!(),
|
||||
//! build: vec!(),
|
||||
//! }));
|
||||
//! ```
|
||||
//!
|
||||
//! If you have multiple `Version`s, you can use the usual comparison operators
|
||||
//! to compare them:
|
||||
//!
|
||||
//! ```{rust}
|
||||
//! use semver::Version;
|
||||
//!
|
||||
//! assert!(Version::parse("1.2.3-alpha") != Version::parse("1.2.3-beta"));
|
||||
//! assert!(Version::parse("1.2.3-alpha2") > Version::parse("1.2.0"));
|
||||
//! ```
|
||||
//!
|
||||
//! If you explicitly need to modify a Version, SemVer also allows you to
|
||||
//! increment the major, minor, and patch numbers in accordance with the spec.
|
||||
//!
|
||||
//! Please note that in order to do this, you must use a mutable Version:
|
||||
//!
|
||||
//! ```{rust}
|
||||
//! use semver::Version;
|
||||
//!
|
||||
//! let mut bugfix_release = Version::parse("1.0.0").unwrap();
|
||||
//! bugfix_release.increment_patch();
|
||||
//!
|
||||
//! assert_eq!(Ok(bugfix_release), Version::parse("1.0.1"));
|
||||
//! ```
|
||||
//!
|
||||
//! When incrementing the minor version number, the patch number resets to zero
|
||||
//! (in accordance with section 7 of the spec)
|
||||
//!
|
||||
//! ```{rust}
|
||||
//! use semver::Version;
|
||||
//!
|
||||
//! let mut feature_release = Version::parse("1.4.6").unwrap();
|
||||
//! feature_release.increment_minor();
|
||||
//!
|
||||
//! assert_eq!(Ok(feature_release), Version::parse("1.5.0"));
|
||||
//! ```
|
||||
//!
|
||||
//! Similarly, when incrementing the major version number, the patch and minor
|
||||
//! numbers reset to zero (in accordance with section 8 of the spec)
|
||||
//!
|
||||
//! ```{rust}
|
||||
//! use semver::Version;
|
||||
//!
|
||||
//! let mut chrome_release = Version::parse("41.5.5377").unwrap();
|
||||
//! chrome_release.increment_major();
|
||||
//!
|
||||
//! assert_eq!(Ok(chrome_release), Version::parse("42.0.0"));
|
||||
//! ```
|
||||
//!
|
||||
//! ## Requirements
|
||||
//!
|
||||
//! The `semver` crate also provides the ability to compare requirements, which
|
||||
//! are more complex comparisons.
|
||||
//!
|
||||
//! For example, creating a requirement that only matches versions greater than
|
||||
//! or equal to 1.0.0:
|
||||
//!
|
||||
//! ```{rust}
|
||||
//! # #![allow(unstable)]
|
||||
//! use semver::Version;
|
||||
//! use semver::VersionReq;
|
||||
//!
|
||||
//! let r = VersionReq::parse(">= 1.0.0").unwrap();
|
||||
//! let v = Version::parse("1.0.0").unwrap();
|
||||
//!
|
||||
//! assert!(r.to_string() == ">= 1.0.0".to_string());
|
||||
//! assert!(r.matches(&v))
|
||||
//! ```
|
||||
//!
|
||||
//! It also allows parsing of `~x.y.z` and `^x.y.z` requirements as defined at
|
||||
//! https://www.npmjs.org/doc/misc/semver.html
|
||||
//!
|

|

//!
|

||||
//! ~1.2 := >=1.2.0 <1.3.0
|
||||
//! ~1 := >=1.0.0 <2.0.0
|
||||
//! ```
|
||||
//!
|
||||
//! **Caret requirements** allow SemVer compatible updates to a specified
|
||||
//! verion, `0.x` and `0.x+1` are not considered compatible, but `1.x` and
|
||||
//! `1.x+1` are.
|
||||
//!
|
||||
//! `0.0.x` is not considered compatible with any other version.
|
||||
//! Missing minor and patch versions are desugared to `0` but allow flexibility
|
||||
//! for that value.
|
||||
//!
|
||||
//! ```notrust
|
||||
//! ^1.2.3 := >=1.2.3 <2.0.0
|
||||
//! ^0.2.3 := >=0.2.3 <0.3.0
|

//! ^0.0.3 := >=0.0.3 <0.0.4
|
||||
//! ^0.0 := >=0.0.0 <0.1.0
|
||||
//! ^0 := >=0.0.0 <1.0.0
|
||||
//! ```
|
||||
//!
|
||||
//! **Wildcard requirements** allows parsing of version requirements of the
|
||||
//! formats `*`, `x.*` and `x.y.*`.
|
||||
//!
|
||||
//! ```notrust
|
